Need to know.
The Bible says that death itself will be destroyed.

“The last enemy that will be destroyed is death.”
1 Corinthians 15:26

Revelation shows us when this happens:

“Then Death and Hades were cast into the lake of fire. This is the second death.” Revelation 20:14

Death is cast into the lake of fire because the lake of fire is where death reaches its final end. The wicked are judged, they suffer the penalty of sin, and they die the second death. Once the last sinner has perished, there is no one left to die.

That is why the next chapter can say:

“There shall be no more death, nor sorrow, nor crying. There shall be no more pain.”
Revelation 21:4

This is the sequence Scripture gives:

the wicked are cast into the lake of fire → they die the second death → death itself is abolished → there is no more death.

Eternal conscious torment reverses that logic. It requires the lost to continue forever in a condition Scripture calls “the second death.” But if death continues forever, how has the last enemy ever been destroyed?

Romans 6:23 gives the same contrast plainly:

“The wages of sin is death, but the gift of God is eternal life…”

The lost are not given eternal life in suffering. Eternal life is the gift of the saved. The wages of sin is death.

The lake of fire does not preserve death forever. It is where death comes to an end.
